V N.- Y.;a co p ration of New. York Application mm 24, 1931, Serial Nms'zosss V 7 T dlZClaims. (or. 91-68) This invention relates to improvements in methods for dressing,itreating and finishing furs,

and has'for-its particular object the provision of a new method or; dressing andtreating furs so that thecompleted furs will be pliable, more waterproof thanunder present methods of treatment, and will showan enhanced lustre.

Another objectfof'my invention is a method of treatingand dressing furs by which their original 10 pliability,- '1ustre:and waterproofing qualities, if impaired, maybe restoredand even improved upon.

Whilst the method of treating and dressing furs herein illustrated is-particularly applicable to rabbit and sheepskins, it'should be understood that u my process is not limited-to these particular kind of skins, but is applicable mother and more expensive furs also.

It is well .understood that in the treatment of 5 a result of these washing, mordanting or dyeing;

processes, many of the natural protective sub- 'stances resident in the skins orin the fur are removed with a consequent tendency of decreas-' ing the pliability or the lustre or the water resist-- with ing qualities of the finishedfurs contrasted the natural furs.

In order to overcome some of the defects caused by these washing, cleaning and dyeing operations,

it has been heretofore proposed to dress the finished skins with .oils and fats of various descriptions so as torestore some of the natural animal fats removed by-these operations.

- This is especially the case, when, as in the of cheaper grades of goods, the whole skins together withthehair have been dyed. by dipping, instead of by the more subtle brushing process,

following this by the" usual drummingoperations 1 in sawdust or otherwise so that a lustrqus'dry polish containing a of extraneous wax material will be left upon thefur, which polish;

will improve the appearance as well as the water while the pliability of the fur is 'retained'or, ir

The complete mixture will therefore consist of 1 gallon of water, 2 ounces of aluminum acetate and 4 ounces of wax emulsion prepared as above described. V I
